Building retrofits are plagued by a lack of original design documentation and general uncertainty regarding the building’s envelope composition and integrity. This presentation shows the power of thermography and transient heat transfer modeling to non-intrusively characterize the thermal properties of a building’s envelope to inform energy modeling, facade design, and project appraisal. We will describe methods to characterize existing building envelope thermal properties, followed by a preliminary methodology to identify representative thermal properties for an existing building envelope.
